Chewonki Semester School Victorious in Maine Wind Blade Challenge

ORONO, Maine - The 7th annual Maine Wind Blade Challenge featured innovative approaches by high school students that pushed the limits of wind blade designs. The event celebrated successes from all students applying their knowledge resulting in the team from Chewonki taking first place, Easton High School placed second and Orono High School's Team 2 placed third out of 41 registered teams.

The 2015 competition also featured a number of other innovative approaches including an electric variable pitch system with an internal accelerometer developed by Freeport High School Students, spreadsheet tools created to compute best design sizes and specs, and teams using hub assemblies with planetary gearing systems created with 3D printers from Old Town High School. The entrants were surprised by the outstanding performance of the first time entrance from Chewonki. The Chewonki team represented the Chewonki Semester School, a challenging semester school emphasizing the natural world, hands-on work, sustainability, and community involvement.

Back Cove Yachts was awarded the composites partner company of the year for their generous work helping multiple teams on their shop floor in Rockland. Paul Sutherland of Easton High School was awarded the teacher of the year award for his work to incorporate composite and renewable energy curriculum in the class room. These awards celebrate the efforts and partnerships this event draws on from industry and educators to be successful.

The competition, held on May 1st, was the culmination of a workforce development program that encourages exploration in innovative design, use of advanced materials, and renewable energy following STEM principles (Science, Technology, Engineering, and Math). The challenge demands the use of academic learning applied to hands on challenges requiring real world solutions. Organized by the Maine Composites Alliance (MCA) and the Maine Ocean and Wind Industry Initiative (MOWII), the program provides advanced material kits, and also opportunities to visit and work with local composite manufacturers and institutes of higher learning. The competition was also supported by the University of Maine College of Engineering and the Advanced Structures and Composites Center.

During the competition sets of blades designed by the teams are testing for electrical output in a competitive setting. The teams must also make a presentation to explain their design and engineering processes to a panel of industry and academic judges. Final scores are based on a combination of the generation output and presentation scores.

The electrical output test measures the electricity generated at wind speeds of approximately 15 MPH. Tests last 2 minutes. During the first 30 seconds of the test the blades operate without any load, the next 30 seconds a load of 20 ohms is introduced by turning on a set of small lights within a model house. Additional sets of lights are turned on every 30 seconds increasing the workloads the blades must respond to, until the 2 minute time limit expires. The accumulative energy output is calculated from the test.

All elements of the event were designed to inspire creativity and innovation. Even the model house with the lights are modeled on the home the home of the character featured in the Dr. Seuss book, the Lorax, which warns of the consequences of not caring for our natural environment. The trophies for the event were created from a technologically advanced commercial scale wind blade section designed by General dynamics, built by TPI composites, and tested at the U-Maine Advanced Structures and Composites Center.

The 2015 competition include a diverse group of students, including teams of all women, all men, mixed gender, advanced college prep students, and technology arts students. Competitors came from all corners of the state - as far north as Easton High School, Jonesport Beals to the east, Fryeburg Academy from the west. Final results can be seen on the web at www.mainewindbladechallenge.com.

"This is an important workforce development program that introduces students to careers in growing technical fields with a high demand for good paying jobs," said Stephen Von Vogt of the Maine Composites Alliance. The opportunity to apply STEM principles to a real world challenge while working work with professional technicians creates unique career exploration opportunities for Maine youth.

Previous students from the competition have gone on to earn degrees at the University Of Maine College Of Engineering, Southern Maine Community College Composites Technician Program, Northern Maine Community College Wind Turbine Technician Program, and the Landing School Composite Boat Building Program. Past participants also now work professionally as engineers, composite technicians and wind turbine technicians in Maine.

The Maine Composites Alliance (MCA) is an alliance of composite businesses in Maine who work together to recognize and promote Maine's leadership in the international composite industry. MCA aims to enhance the competitiveness of Maine's existing composite industry by providing opportunities for new commercial ventures, and by providing education and training for members and their employees.

The Maine Ocean and Wind Industry Initiative (MOWII) represents companies' expertise within the Maine ocean and wind energy supply chain, works proactively to promote the expertise of member companies, provides solutions to local, national, and international market participants, and provides industry and public educational opportunities.

The College of Engineering at the University of Maine (COE) is the sole institution in Maine to offer 11 engineering and engineering technology majors and full M.S. and Ph.D. programs. The College of Engineering is working for Maine to educate and train the next generation of engineers to meet the growing technological needs of our state, and to develop the innovations needed to power Maine's economy.

The Advanced Structures and Composites Center is a state-of-the-art one-stop-shop for integrated composite materials and structural component development. Located at the University of Maine, it offers in-house capabilities for developing a composite product or structure from the conceptual stage through research, manufacturing of prototypes, comprehensive testing and evaluation, code approval and commercialization.

Wind Blade Challenge was created to inspire, motivate, engage, and introduce students to the world of STEM education, composites and alternative energy with the purpose of building a strong workforce in the composite and alternative energy industries. Students from past competitions are now working in the Maine composites, wind industry and/or continued their education in STEM fields. http://mainewindbladechallenge.com/
